MAX34417 SMBus Four-Channel High Dynamic Range Power Accumulator General Description Benefits and Features The MAX34417 is a specialized current and voltage Enables Code Optimization to Minimize Power monitor used to determine power consumption of portable Consumption in Portable Platforms systems. The device has a very wide dynamic range Four Power Monitors with Wide 86dB Dynamic (20,000:1) that allows for the accurate measurement of Range power in such systems. The device is configured and Measures Both Current and Voltage 2 Low Power Consumption monitored with a standard I C/SMBus serial interface. The unidirectional current sensor offers precision high- Reduced Power Consumption in Slow Accumulation Mode side operation with a low full-scale sense voltage. The device automatically collects the current-sense and voltage Power-Down Mode samples and then multiplies those values to obtain a Minimizes Processor Overhead with Autonomous power value it then accumulates. Upon a command from Operation the host, the device transfers the accumulated power Per Channel 56-Bit Power Accumulators Capture samples, as well as the accumulation count, to a set of 4.55 Hours of Data at 1024 Samples per Second registers accessible by the host. This transfer occurs without Per Channel 14-Bit Voltage Registers missing a sample and allows the host to retrieve the data High-Integration Solution Minimizes Parts Count, not in real-time, but at any time interval.
